Solution Overview
Problem
The high viscosity of aerosol-forming substrates in vaporization devices leads to unsmooth liquid feeding, causing burnt taste in aerosols and reducing the service life of vaporization assemblies due to drying heating.
Innovation Solution
A vaporizer design featuring a preheating member thermally connected to the vaporization assembly, extending into the liquid storage cavity to preheat aerosol-forming substrates, reducing viscosity and improving feeding smoothness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerosol-forming substrates with high viscosity are used, then the vaporization device can deliver inhalable aerosols to users, but liquid feeding becomes unsmooth and the vaporization assembly absorbs liquid slowly
Solution Approach 1:
The preheating member is positioned to preheat the aerosol-forming substrate before it reaches the vaporization assembly. This preliminary heating action reduces the viscosity of high-viscosity substrates in advance, enabling smooth liquid feeding and preventing drying heating at the vaporization assembly, thereby resolving the contradiction between aerosol delivery capability and liquid feeding smoothness
2Productivity
If high viscosity aerosol-forming substrates are vaporized, then aerosols can be produced for inhalation, but the vaporization assembly experiences drying heating that reduces its service life
Solution Approach 1:
The preheating member performs preliminary heating of the aerosol-forming substrate before it reaches the vaporization assembly. This prevents the substrate from causing drying heating when it contacts the heated vaporization assembly, thereby extending the service life of the vaporization assembly while maintaining aerosol generation capability
Solution Approach 2:
The preheating member acts as an intermediary between the aerosol-forming substrate and the vaporization assembly. It prepares the substrate by reducing its viscosity through preheating, so that the substrate is in optimal condition before reaching the vaporization assembly, preventing harmful thermal effects and extending component life
